Prosecutors say she lied on applications to enter the country as a refugee in 1995 and to obtain citizenship in 2003. She was sworn in as a citizen in the same federal courthouse where she's now on trial. On those applications, Munyenyezi denied any role in the genocide or affiliation with any political party during the slaughter of 800,000 Tutsis and moderate Hutus.

Prosecution witnesses have placed Munyenyezi at a checkpoint where Tutsis were identified and ordered killed. Her lawyers say she's innocent.
